Abstract:
Objective:To Compare the difference between the data of normal lumbar plexus nerve measured through magnetic resonance neurography(MRN) with specimen. Methods:Volunteers of 30 healthy lumbar plexus nerve cases(19 males and 11 females) were selected, to measure the short shaft line and neuromuscular signal ratio of the right normal lumbar nerve root, ganglia, nerve and the femoral nerve stem, anatomy and measurements of the right lumbar plexus L2~5 nerve root,ganglia and nerve stem, femoral nerve morphology and size. And comparison of MRN measurement data and autopsy measurement data were conducted. Results:MRN could clearly show L2~5 nerve course, ganglion being circle or Oval enlargement, with the size about 3~6mm;a nerve root and stem displayed strips and smooth edge, with the size about 2~5mm, nerve Festival signal is more than the nerve root and stem. There was no significant statistical difference with the comparability between the obtained data and autopsy ones. Conclusion:MRN can clearly show lumbar plexus and major branches; its measured value can reflect changes in lumbar plexus. It is possible for diagnostic criteria of the lumbar plexus nerve diseases and dysplasia.
